However this process is frequently required in research and quality assurance contexts. The purpose of this study was to examine inter-rater reproducibility agreement and reliability among an inexperienced group of clinicians in extracting spinal pathoanatomic information from radiologist-generated MRI narrative reports. Methods Twenty MRI narrative reports were randomly extracted from an institutional database. A group of three physiotherapy students independently reviewed the reports and coded the presence of 14 common pathoanatomic findings using a categorical electronic coding matrix. Decision rules were developed after initial coding in an effort to resolve ambiguities in narrative reports. This process was repeated a further three times using separate samples of 20 MRI reports until no further ambiguities were identified total n 80 . Reproducibility between trainee clinicians and two highly trained raters was examined in an arbitrary coding round with agreement measured using percentage agreement and reliability measured using unweighted Kappa k . Reproducibility was then examined in .
